I Specification of Letters Patent. Application filed 1 m 11.1906. Serial it). 311.157. p i

Patented Dec. 24, 1907,.

To all whom it'may concern: a

Be it known that I, :FREDERIGKJ. HEY- BAOH, a citizen of the United States, residin at Savannah, in the county of Chatham an State of Georgia, have invented new and useful Improvements in Weighing'and Can-Fillpparatus", of which the followingis a specification. s p Y a This invention relates to weighing and can filling apparatus, the object of the invention.

. being to provide simple apparatus of this kind material into cans or equivalent receptacles,

primarily intended for ivering charges of and this the machine can ,do in a rapid manner without waste.

In the drawing accompan ng and forming part of this specification I s ow in longitudiweighing device which, as will herea more particularly appear, is substantially the same as that disc osed in Letters Patent No. 791,342 granted to me Ma -30, 1905, and

to which reference may be ha Thedifierent parts of the a paratus may be supported in any desirab e way. The framework shown in part for this urpose is denoted in a-general way by 2. I ans to be filled, and only one of which is represented in the drawing, are fed along a wa as 3 between strips as 4, only one of whic is shown, by means of chains or the like connected by slats as 5. The feed chains or equivalent means impart to the cans a step b; movement, the parts being so relate that, when'the feed chains are at rest, a can will be inposition to receive a'charge of material from theweighing device, althou h the can 6 in the drawings is" supposed to e moving in the direction of the arrow, having received a charge of material. Said can, when in position to receive said charge, is sustained upon suitable supporting means, as the crosspiece 7, in connection with which tapping mechanism such-as that denoted in a general step way by 8, is operative. This tapping mechanism forms no part. of the present invention,

for which reason it need not be shown or de scribed in detail; it, however, is fully shown and claimed in my concurrentl pending application, Serial No. 334,181, ed Sept. 11, 1906. While the can 6 is on the supporting cross-piece 7 or similar part it is sub ected to the action of said tapping mechanism.

The weighing device comprises a scale beam as 9 to which is connected the weighing bucket or hop or 10. The bucketor'hopper 10 is equipped with a closer Or'discharge gate 11 carrying exteriorly thereof the arms 12 and 13 engageable alternately by a power- 0 erated reciprpcatory member as 14. When t e reci rocatory member 14 is moved toward t e right, the pin 15 on thedepending arm 16 thereof strikes the arm13 to thereby o n the closer or valve 11 to permit the di schar e of the contents of the bucket or weighing hopper 10. On the retractive or'backward movement of said i member 14 the pin 15 strikes the arm 12 for the purpose of closing said valve or closer 11. The; weighing device and. its adjuncts just described may be and preferably are. of the character shown in the-Letters Patent to which I have referred, for which reason an extensive description of the same is unnecessary.

The materlal may be supplied to the weighing hopper or bucket 10 from a supply ho er as 17 the stream from which is contro ed by a valve as 18 o erable by mechanism denotedin a general way by 19. The valve-operating mechanism formsin itself no part of the present invention, for which reason it need not be set forth in detail herein. It is fully set forth and claimed,

however, in my contemporaneously pending application Serial No. 334,180, filed Sept. 11, 1906.

The loads of material successively dis-- charged from the bucket 10 are guidedinto empty cans by a tube such as that denoted in a .general way by 20. The tube 2 -0 is shown as comprising two sections, an inner section as 21 and an outer section as "22',

said inner section being illustrated as'being;

of funnel shape and being fastened in some suitable manner at its upper end to the lower endof the bucket 10; Said funnel guides the mass 4 of material into an empty of the can.

,31 for engaging the bracket 24.

can, although in the present case its lower edge does not come directly to the top I prefer to provide suitable means, as will hereinafter appear, to cover the gap between the lower end of the section 21 and the upper edge of the can, so as to prevent the passage of material through this gap. The funnel or inner section 21 will be so connected with the bucket 10 as to prevent the escape of material between suc 1 two parts. The outer section 22 has directly uncer said l'unnel so that, when the load is discharged from the bucket, the funnel Wlll guide the load into the empty can,

while the packing assisted b y the outer sec tion 22, W1

l prevent escape of any of the material, which is particularly ol advantage when the material is highlypulverulent, such for instance as yeast powder.

On the exterior of the tubular section 22 is fastened suitably a bracket as l from which rises one or more spindles as guided for reciprocation by guide brackets as 28 on the framework of the machine, said spindle or spindles being surrounded by a spring or springs 29 acting against the bracket or brackets 28 and bracket 24, respectively. The spring or springs 29 serve to impart adownward thrust to the bracket 24 for lowering the tubular section 22 for the purpose of carrying the packing 23 into engagement with the upper edge or top of the can 6 when the latter is on the support. 7. An intermittently pmvcr-operalcd cam is shown at 30 and this cam serves to actuate an angle lever as 31, the normally horizontal arm of which is equipped with a member as The cam 30 has a let-oil or releasing portion 1-3.. The active portion of the cam 30 is shown in enagement with the upper end of the angle ever 31 so as to maintain the telescopic section 22 through the intermediate parts in its upper position. When, however, a cam as 6 has been positioned on the support 7 with said cain under the funnel 21, it being assumed that the cam 30 is turning at this time, and when the releasing portion 32 of said cam comes opposite the angle lever 1H,

the spring or springs 25) may operate to thrust the bracket 24 and thereby the tubular section 22 downward to carry the packing 23 into engagement with the upper man of material is discharged from the bucket 10, the material constituting the same cannot be wasted, for not only is the load delivered in an accurate manner into the can, but all scattering of the material is prevented. hen the material is delivered into the can the operative portion of the cam 30 by acting against the angle lever Ill, returns the tubular section 22 to its Zilltlitl or elevated position. it will be inani-rstood that the cam normally holds the iubulnr section 23 up with the packing in a pin no above the tops of the cans.
